LOGGING-CAR.

SPECIFICATION forming part of Letters Patent N 0. 552,346, dated December 31, 1895.

Application filed June 10, 1895. Serial No. 552,258. (No model.)

To all whom it may concern:

Be it known that I, FIRMIN BEDARD,of Minneapolis, in the county of Hennepin, State of Minnesota,have invented certain newand useful Improvem ents in Logging Cars, of which the following is a specification.

My invention relates to laterallytilting cars, and particularlyto that class of cars that are used for transporting logs from place to place; and the object I-have in view is to provide a mechanism by means of which the car may be easily tilted to facilitate the removal of the logs; and a further object is to provide view showing the car tilted.

a gripping device arranged to hold the chain passing over the logs securely in position, and automatically to release the same when the car is tilted.

My invention consists generally in various constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of a logging-car embodying my invention. Fig. 2 is a sectional view on the line 00 00 of Fig. 1. Fig. 3 is an end View of the car in a horizontal position. Fig. 4 is a similar Fig. 5 is a side elevation showing the tilting or dumping mechanism. Fig. 6 is a detail View of the gripping device, showingthe jaws open. Fig. 7 is a similar view showing the jaws closed. Fig. 8 is a sectional view on the line y y of Fig. '7. Fig. 9 is a detail View of a portion of the tilting mechanism. Fig. 10 is a detail of the mechanism for holding the outer bottom log in position on the car. Fig. 11 is a sectional detail view of the bearings for the tilting portion of the car, showing the king-bolt passing down through the same.

In thedrawings, 2 and 3 represent crosstimbers arranged at each end of the car, and at and 5 are longitudinal timbers resting upon the cross-timbers,and near the central portion thereof. The cross-timbers are provided with longitudinal rods or braces, as is usual in cars of this construction. Immediately above the cross-timbers and resting upon the longitudinal timbers 4 and 5 are the cross-timbers or bunks 6 and 7, which support the tilting portion of the car.

The timbers 6 and 7 are rigidly secured to the longitudinal timbers 4 and 5 by suitable straps or braces, as shown in Fig. 5.

The timbers 6 and 7 are each provided near their central portion with the castings 8 having the laterally-extendin g flange 9, by means of which the castings are secured to the sur-,

face of the cross-timbers; and the casting is also provided with an upwardly-extending flange 10, and with the convex bearing-surface 11, having a central opening 12 extending down through the convex portion, said opening being slightly flared at the top for the purpose hereinafter described.

Above the timbers 6 and 7 and supported thereby is the body or tilting portion of the car, comprising the end cross-timbers 6 and 7, the longitudinal timbers 15 and '16 connecting the end timbers, and the bar or brace 17 connecting the middle portion of said longitudinal timbers. These parts are all securely bolted together, and the end timbers 6 and 7 are each provided upon their under side with a casting or plate 18 having a concave surface 19 to bear upon the face 11 of the part 8, and also having a shoulder 20 to engage the flange 10 whereby the travel of the car-body is limited. The parts 18 are also provided with a vertical hole or opening through which the king-bolt 22 passes. The bolt extends down through the cross-timber, and is provided in its lower'end with a slot 23 to receive a key or pin 24 which prevents the car-body from becoming detached from the frame.

Mounted in bearings 25 upon the timbers 6 and 7 and extending beyond either end of the car-body is a shaft or rod 26, as shown in Fig. 5. The timbers are provided upon their outer surface near the opposite end from the bearings 25 with the pins or studs 27, arranged to operate vertically in guides 28 secured to the outer face of said timbers. A link 29 is pivoted at one end to the lower end of the pin, and the opposite end of the link .29 is pivoted to a longer link 30 that is pivoted near its center in a guide or bracket 31 that is secured to the lower edge of the timbers 6 and 7. From the lower end of the links 30 rods 32 extend across the car parallel to the timbers 6 and 7, and having their opposite ends pivotally secured to downwardly-extending lugs 33 011 the collars 3i rigidly secured on the shaft 20.

Upon the inner face near the opposite end from the shaft 26 of each of the timbers 6 and 7 and O and 7 are pivoted respectively the links or toggles 35 and 30, having their abutting ends pivoted together and to rods 37 that extend across the car and are pivoted to lugs 38 on the collar 39 rigidly secured on the Shaft 26.

Pivoted to the under side of the cross-bar 17 in position to engage the chain that is passed through the opening 40 in the end of said bar are the curved jaws 41. The jaws are slightly bow-shaped so that when the inner ends are separated the outer ends will be brought together to clasp a link of the chain, and hold it securely. A bar 42 is arranged to move laterally between guides 43 on the under surface of the cross-bar 17, and provided at one end with a wedge-shaped part to pass between the curved inner ends of the jaws 4C1, whereby the outer ends will be brought together to clasp the chain. A strap 41 is secured to the end of the bar 42 and embraces the jaws 41 so that when the bar is drawn back the jaws will be opened, and stops are provided on the timber 17 to limit the backward movement of the bar 42. The opposite end of the bar 42 is pivotally secured to a lug M on a collar l5 that is fixed on the shaft 20. One end of the shaft 26 is squared to receive a square opening provided in the end of the lever or crank 4:6, by means of which the shaft may be rocked. Secured to the frame of the car near the squared end of the shaft 26 is a notched bar a7, and pivoted to the cross-timber 6 on the car-body is a pawl or dog i8 in position to engage the notched bar, and by means of which the car-body when tilted may be held in any desired position, and prevented from falling back when it is desired to remove the lever or crank at the end of its stroke.

-""'4-5"-Pivoted or bolted to the longitudinal timber 16 is a ring 49 into which one end of the chain is hooked that passes over the logs, and extending from the inner upper surface of the cross-timbers 6 and 7 between the timbers 4: and 5 down to a point beneath the cross-bar 17 are the braces 50 and 51, which serve to strengthen the car-body. The timbers 6 and 7 are provided with fixed studs 52 and 53 which prevent the logs from rolling off the side of the car upon which the tilting mechanism is located.

\Vhen the car-body is in its normal horizontal position the studs 27 will project above the upper surface of the timbers G and 7, as shown in Fig. 3, and the links 35 and 36 will be in the position indicated by solid lines in Fig. 9, and when the links are in this position the car-body will be locked, and held in this position until the links are thrown into the position indicated by dotted lines in Fig, 9 by the rocking of the shaft 26. As the shaft is rocked by the upward movement of the lever 40 the car will be tilted, the pins 27 drawn down, the jaws opened, and the logs permit-- ted to roll from the car.

IIeretofore the services of several attendants have been required to unhook the chains and roll the logs from the car, and it frequently happened that the attendants were severely injured, if not killed outright, by the logs as they rolled from the car, it being almost impossible to get out of the way after unhooking the chain.

lVith the use of the mechanism which I have shown and described one attendant can operate the mechanism for tilting the car, and at the same time release the chain and allow the logs to roll from the car without any danger to his life or limb. The central opening in the casting 8 being flared at the top permits the kin g-bolt to move laterally and allows the car-body to tilt when the shaft 20 is rocked.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a device of the class described, the combination with the truck frame, of the tilting car platform mounted thereon, means for retaining said car platform in a horizontal position and means for tilting the same, the clamping jaws, the vertically movable studs carried by said car platform, and extending above the upper surface thereof, and means for simultaneously drawing down said studs, and opening said jaws, substantially as described. 11
